Associative Patterns Between Iron Deficiency Anemia and Febrile Seizures in the Five to 60 Months Age Group: A Comprehensive Systematic Review

Posted by in category: neuroscience

Convulsions developed due to temperatures above 38°C (100.4°F) are termed as febrile seizures (FS). These seizures are not caused by any central nervous system infections (CNS) or any metabolic abnormalities. Essentially, it occurs in individuals without a prior history of afebrile seizures [1]. It is the most commonly observed seizure type in children under five years of age [1]. Roughly one-third of children who have one FS may experience a second. Among children with simple FS, 1% to 2% may develop epilepsy. In contrast, those with complex FS have a higher risk, with 6% to 8% later being diagnosed with epilepsy [2].

Iron deficiency and iron deficiency anemia (IDA) are pervasive on a global scale. Roughly 30% to 40% of people worldwide suffer from IDA, with the majority residing in developing nations [3]. IDA has stood as the primary contributor to the healthcare burden in India over the last 10 years [4]. Iron deficiency can adversely affect the developing brain in multiple ways. It can impair hippocampal neuron growth and disrupt the myelination process, which insulates nerve fibers for efficient signaling. This deficiency can also impact the metabolism of neurotransmitters such as monoamines and aldehyde oxidase, resulting in lower neurotransmitter levels and a potential decrease in the seizure threshold. Moreover, low serum ferritin levels in conjunction with fever can compound the adverse effects on the brain, potentially leading to seizures [5]. Notably, it’s worth mentioning that the peak ages for FS and IDA coincide [5]. While certain studies identified a link between FS and anemia resulting from iron deficiency [6–16], other research yielded divergent findings [17–20]. The primary objective of this study is to find the association between IDA and FS in children by doing a systematic review of the literature of the last 10 years. The secondary objective is to understand the significance of the iron profile in FS.

This study is a systematic review done in accordance with Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) guidelines.

Artificial nanofluidic synapses can store computational memory

Posted by in categories: computing, neuroscience

Memory, or the ability to store information in a readily accessible way, is an essential operation in computers and human brains. A key difference is that while brain information processing involves performing computations directly on stored data, computers shuttle data back and forth between a memory unit and a central processing unit (CPU). This inefficient separation (the von Neumann bottleneck) contributes to the rising energy cost of computers.

How Blood Sugar Changes Affect Thinking in Folks With Type 1 Diabetes

Posted by in categories: biotech/medical, neuroscience

MONDAY, March 18, 2024 (HealthDay News) — In people with type 1 diabetes, fluctuations in blood sugar levels can affect thinking skills in various ways, new research shows.

Researchers looked specifically at what’s known as cognitive processing speed (how fast people process incoming information) and attention.

“Our results demonstrate that people can differ a lot from one another in how their brains are impacted by glucose,” said study co-senior author Laura Germine.

Grimes Using Custom Brain Interface From Elon Musk Competitor

Posted by in categories: computing, Elon Musk, neuroscience

Year 2023 😗😁


Famed musician and former Elon Musk boo Claire “Grimes” Boucher wanted a brain-computer interface (BCI) for her birthday — and one of Neuralink’s apparent competitors was happy to comply.

After Grimes tweeted about getting a “non invasive brain computer interface” for her birthday, AJ Keller, the CEO of the startup Neurosity, confirmed in an interview with Insider that his firm had indeed made a custom brain gadget for the “Kill V. Maim” singer.

Teens’ Transcendent Thinking Spurs Brain Growth

Posted by in categories: education, neuroscience

Summary: Adolescents engaging in “transcendent thinking”—the practice of looking beyond the immediate context to understand deeper meanings and implications—can significantly influence their brain development. The study highlights how this complex form of thinking fosters coordination between the brain’s executive control and default mode networks, crucial for psychological functioning.

Analyzing high school students’ responses to global teen stories, researchers found that transcendent thinking not only enhances brain network coordination over time but also predicts key psychosocial outcomes in young adulthood. These groundbreaking findings underline the potential of civically minded education in supporting adolescents’ cognitive and emotional development.

Researchers find branched chain amino acid supplementation may aid in concussion recovery

Posted by in categories: biotech/medical, neuroscience

In the first clinical trial of a targeted pharmacologic therapeutic for mild traumatic brain injury in pediatric patients, scientists from the Minds Matter Concussion Frontier Program at Children’s Hospital of Philadelphia (CHOP) have found preliminary evidence that adolescents and young adults with concussion who take a specific formulation of branched-chain amino acid (BCAA) supplements after injury experience faster symptom reduction and return to physical activity.

Effects of Physical Rehabilitation With X-Sens Inertial Technology Feedback on Posterior Cerebral Artery Infarcts: A Case Study

Posted by in categories: biotech/medical, neuroscience

Read this fascinating case study on the impact of physical rehabilitation using X-Sens Inertial Technology feedback for Posterior Cerebral Artery Infarcts! 🧠.


Acute ischemic stroke (AIS) affecting the posterior cerebral artery (PCA) represents a unique clinical challenge, necessitating a multifaceted approach to rehabilitation. This review aims to provide a comprehensive overview of physiotherapeutic interventions tailored specifically for individuals with AIS involving the PCA territory. The PCA supplies critical areas of the brain responsible for visual processing, memory, and sensory integration. Consequently, patients with PCA infarcts often exhibit a distinct set of neurological deficits, including visual field disturbances, cognitive impairments, and sensory abnormalities. This case report highlights evidence-based physiotherapy strategies that encompass a spectrum of interventions, ranging from early mobilization and motor training to sensory reintegration and cognitive rehabilitation.

How Fear Unfolds inside Our Brains

Posted by in categories: biotech/medical, chemistry, neuroscience

The stress-induced mechanisms that cause our brain to produce feelings of fear in the absence of threats have been mostly a mystery. Now, neurobiologists at the University of California San Diego have identified the changes in brain biochemistry and mapped the neural circuitry that cause such a generalized fear experience. Their research, published in the journal Science on March 15, 2024, provides new insights into how fear responses could be prevented.

In their report, former UC San Diego Assistant Project Scientist Hui-quan Li, (now a senior scientist at Neurocrine Biosciences), Atkinson Family Distinguished Professor Nick Spitzer of the School of Biological Sciences and their colleagues describe the research behind their discovery of the neurotransmitters — the chemical messengers that allow the brain’s neurons to communicate with one another — at the root of stress-induced generalized fear.

Studying the brains of mice in an area known as the dorsal raphe (located in the brainstem), the researchers found that acute stress induced a switch in the chemical signals in the neurons, flipping from excitatory “glutamate” to inhibitory “GABA” neurotransmitters, which led to generalized fear responses.
